DTMF based security Robot-SECBOT an ease for un-manned security

This Research involves the current technologies like DTMF (Dual Tone Multi-Frequency); GSM module; sound sensor; GPS locator which are present in a smart phone, which are combined together to retort out the issue of Security. DTMF is a methodology used by the help of phones for the communication signalling on telephone lines in the voice-frequency band between a user and the switching device. Whereas the sensors like sound sensors are used in a manner where the quantities like sound are converted into electronics understandable language. The operations which we have used here are for availing humans the facility of security purposes as well as for the defence system of a country; controlled by the help of a simple cell phone which they often use in their life. For having great versatility and various applications with key features such as GPS location, automatic obstacles avoidance, thief sensing, edge detection and hence giving an alert to the user in the form of text message or a call. This is how we can easily use this rover in different aspects for home security as well as in different other fields by the help of modification and advancing technology of programming and interfacing.
